AI Rally Lifts Markets as Oil Prices Drop

Stock markets saw a boost at the start of the week driven by strong investor reaction to Meta's new AI assistant Muse and declining oil prices. Meta surged over 11% on Monday, while broader AI-related stocks also rose after weeks of concern about potential risks from artificial intelligence. Chipmaker AMD reached a $1 trillion market valuation as global chip stocks climbed again. Meanwhile, geopolitical tensions remained in focus ahead of Thursday's summit between U.S. President Donald Trump and Chinese leader Xi Jinping, where AI regulations and trade issues are expected to be discussed. Hopes for diplomatic progress were reflected in falling crude prices after reports that Iran offered to reopen the Strait of Hormuz if the U.S. reduces military pressure. In Europe, French debt underperformed due to uncertainty over a budget agreement amid next year's presidential elections. The yield spread between France and Germany hit its highest level in more than 10 years.
